When you think about it, the enterprise workstation market really only has three key players. You have HP, who produce some excellent mobile workstations but have been stagnating horribly on the desktop side. You have Dell, who produce what are in my opinion the best desktop workstations but seem to be substantially less exciting on the notebook end. And you have Lenovo, who excels in neither discipline but offers a fairly balanced portfolio in exchange. This presents a problem, and it's a problem we're looking at today.

What we really want and need is a single vendor to order notebooks and desktops from and be able to call it a day. While HP's desktops aren't bad, they're overpriced compared to Dell's offerings. Today we have the updated Dell Precision M6700 on hand, a robust notebook featuring a full sRGB IPS panel with user-configurable gamma, a Kepler-based workstation GPU, and Intel's Ivy Bridge quad core processor. But with workstations it's not just about the internals, it's about the design and the experience. Did Dell come up with a worthy competitor to HP's EliteBooks, or did they just come up short?

Three years ago, this wasn't the way things were. HP had great desktops and Dell had great notebooks, but the situation seems to have almost completely flipped. The design language on HP's enterprise class notebooks suddenly unified, offering a combination of style, serviceability, usability, and performance that was able to compete with Dell's Precision line as well as Lenovo's sadly declining ThinkPads. As you'll see, though, just as HP's desktop workstation department seems to be coasting, Dell's mobile workstation department is having a hard time playing catch-up.

On the hardware side, the Dell Precision M6700 certainly has a lot going for it. While Dell's BIOS doesn't allow for any overclocking, the Intel Core i7-3920XM is still an incredibly fast processor, with a nominal clock speed of 2.9GHz, able to turbo up to 3.6GHz on all four cores, 3.7GHz on two cores, or 3.8GHz on one core. These turbo speeds put it within striking distance of desktop Ivy Bridge CPUs.

The NVIDIA Quadro K5000M is an interesting story in and of itself. While last generation's mobile workstation GPUs continued to be served by die harvesting GF100, the K5000M inherits all the strengths and disadvantages of GK104. Single precision performance should be top flight, but GK104 is more of a gaming chip than a compute chip (similar to GF104/GF114), and so its double precision performance is liable to be below last generation's Quadro 5010M, and we'll see when we get to the workstation benchmarks. For this reason, the 5010M continues to be available. The K5000M is clocked slower than the current top of the line mobile gaming GPU, the GTX 680M, running at just 601MHz on the CUDA cores and 3GHz effective on the GDDR5, with no boost clock.

Internally, Dell also offers an mSATA port at SATA 6Gbps speed as well as two 2.5" drive bays and the ability to remove the optical drive and replace it with a third 2.5" bay, allowing for potentially four storage devices. Also included are a SIM card slot and space for a WWAN card. Externally you have a card reader, USB 2.0 and 3.0, ExpressCard/54, 6-pin FireWire, eSATA, and every modern display connector except DVI.

Rounding out the trimmings, our review unit has Dell's PremierColor IPS display which is touted to offer the full AdobeRGB gamut; this is essentially to compete with HP's own DreamColor display. Unfortunately we did run into some issues with PremierColor and our calibration/measurement software, ColorEyes Display Pro, which we'll discuss later on. But Dell has a healthy number of choices for displays, including a basic 900p display, 1080p, 120Hz 3D Vision Ready 1080p, and the PremierColor IPS panel.

For what its worth, WiFi-ac is the only one of these subjects that I have any sympathy for the manufacturers on.

It is THIS year's nascent technology. Its hard, but not impossible to get this year's new tech onto a machine.

I use the laptop at home primarily, and infrequently in the field.

In the field I need autonomy for up to 2 months at a time, sometimes in very far flung places with little else available infrastructure-wise besides mains power and maybe 3G or 2G GSM. Hence the obsession with local storage, but I digress.

At home, I have ADSL.

The NetGear WiFi-ac router R6300 is available now at Amazon. I think it is 3 x 3 so you might get close to Gigabit WiFi speeds, or in actual practice, maybe 75% of Gigabit WiFi speeds. That's a very impressive boost over WiFi-n.

The equivalent NetGear ADSL Gateway Modem with built in WiFi-ac Router is the D6300. It is currently available at Amazon UK and should be available stateside any day now.

WiFi-ac is today's reality. Why buy an uber-expensive laptop this year when next year's model will have wireless that is 5 times faster...

Unless you want to gamble on the upgrade working.

I hope that you are correct that these machines can be upgraded from WiFi-n to WiFi-ac with a simple mini-card replacement.

But, when I tried to upgrade my existing ancient HP 17" from WiFi-g to WiFi-n, it didn't work. So I emailed HP and asked why. They said that for the newer WiFi-n mini-cards to be compatible, the BIOS needed to be changed and that HP wasn't willing to issue the necessary BIOS revision.

Granted my machine isn't a mobile workstation (it is one grade below that). I would hope that in the future if I pony up the cash for a mobile workstation class machine, that the manufacturers would be more accommodating with BIOS revisions than what I've experienced with the "desktop replacement" class laptop that I have now.

So? You connect to your own company network by cable anyways, and if you are traveling, what are the chances that even if you find a WiFi-ac connection that there is an Internet-Connection behind it that is actually fast enough to utilise -ac speeds? Reply

I am a M6700 owner. The IPS display causes the loss of Optimus. This is due to the display chain being pure 10-bit throughout which the Intel HD 4000 can't do.

As far as SIM slots and GPS goes... Dell's online configuration tool won't allow you to add these but they all come with a SIM slot and antenna leads for a WWAN (and GPS) module regardless of the screen you pick can be added separately. I'm running the Dell 5630 (Gobi 3000) without any issues that I added myself.Reply
